A late model Northstar isn't returnless? I'll have to go take a gander when I finally change my oil this weekend. Thought GM implemented it across the board on their engines by around '01/'02 for emissions purposes?

The heater made the system go lean. I put a larger fuel jet in and turned up the fuel pressure 10%, but it still goes lean. I plan on dropping the fuel pressure 5% and making so more runs. The heater really helped getting consistent runs.

I love it!!! I know it's not track slips, but the differences off the info off of the data logs and tech2, w/ n.o.s. and without are astounding, obviously it's a whole different animal on the go-go juice. We'll get her down to the track soon, just been so crazy lately, but will get it down to show off a amazing time slip soon to come.

The System has been going lean for a few weeks and we have not run it at the track for that reason.

I Called Craig @ Nitrous Express and he told me that the rubber on the Fuel Solenoid Plunger could be swelling up. He asked me to check the color of the rubber and call him back. I removed the plunger and the seal looked fine to me. I called he back and told him it was tan in color. He asked me if the rubber was flush with the stainless steel. I replied No it is not. Hmm
The fuel swelled up the seal and has been making my lean condition. Craig sent me out a special replacement Fuel Solenoid.

Well, I have heard reports of the ethanol in E10 wrecking the plunger gaskets on fuel noids. I think you may see quite a few more people toasting motors on spray now that E10 is pretty much country wide in its use. Supposedly NX was using a new gasket material, I think viton instead of rubber and has been for a couple of years. Was your kit new or used, I can't remember?

Re: How to install Nitrous the correct way! I need input

Brand new. The fuel solenoid leaked when initially installed, so it's been suspect from the beginning. This crap gas finished it off? Apparently NX has a different better updated design for the crap gas, specify when you order, I guess. They're sending one.

One more thing to add
Craig mentioned Winter and Summer blends.
Maybe we started with a Winter blend and the Summer blend killed it.

We have 3 different types of Data Loggers, so we will know if the Summer blend needs more fuel by weight.

We are finally heading to the track.

We have had a few problems that developed after having the system on the car for a few weeks.
#1 the car was going lean after the Bottle heater was installed.
#2 Rain rain and more rain.
#3 My schedule

The lean condition may have been caused by a plunger in the fuel solenoid. The original plunger had a tan rubber insert in the end of it. The fuel in our area caused the rubber portion to swell out past the end of the metal portion. I was informed that the plunger travels about .030 of an inch and the rubber was out about .015". The new plunger NX sent me had a black rubber material and it is actually recesses in the metal portion
